If the reflected ray is rotated by an angle of `4theta` in clockwisse direction then the mirror was rotated by

I is a ray incident on a plane mirror. Keeping the incident ray fixed, the mirror is rotated by an angle theta about an axis passing through A perpendicular to the plane of the Fig. show that the refracted ray rotates through an angle 2theta . Does your answer differ if the mirror is rotated about an axis passing through B?

Correct the following sentences if required: The reflected ray is found to rotate through an angle of 60^@ . Then the plane mirror must have rotated through 120^@ .

Show that a ray of light reflected from a plane mirror rotates througha an angle 2theta when the mirror is rotated through an angle theta about its axis perpendicular to both the incident ray and the normal to the surface.

Show that a ray of light reflected from a plane mirror rotates througha an angle 2theta when the mirror is rotated through an angle theta about its axis perpendicular to both the incident ray and the normal to the surface.

Show that for a given incident ray, if the mirror is rotated by an angle theta , the reflected ray rotates by 2theta .

A soldier directs a laser beam on an enemy by reflecting the beam from a mirror. If the mirror is rotated by an angle theta , by what angle will the reflected beam rotate?

a ray of light is incident on a plane miror at an angle of 30^(@) in anti-clockwise direction. Find the angle and sense of rotation of the reflected ray.

a ray of light is incident on a plane miror at an angle of 30^(@) in anti-clockwise direction. Find the angle and sense of rotation of the reflected ray.

A ray of light travels from a light source S to an observer after reflection from a plane mirror. If the source rotates in the clockwise direction by 10^@ , by what angle and is what direction must the mirror be rotated so that the light ray still strikes the observer?
